At some point during Cincinnati's final practice on Friday, heading into the Kansas City Chiefs game last week, Bengals wide receiver Andrew Hawkins suffered a knee injury. He was limited that day (probably meaning he suffered it during team drills, preventing him doing team participation) and sat against the Chiefs on Sunday.
Lewis told the media earlier this week that Hawkins was more of a day-to-day thing. On Wednesday Hawkins didn't practice with the team, making the probability of playing against the Oakland Raiders a little less likely.
